Many biological and man-made networked systems are characterized by the simultaneous presence of different sub-networks organized in separate layers, with links nodes qualitatively types. While during past few years theoretical studies have examined a variety structural features complex networks, outstanding question is whether such characterizing all single or rather emerge as result coarse-graining, i.e. when going from multilayered to aggregate network representation. Here we address this...

This paper examines the relationship between street centrality and densities of commercial service activities in city Bologna, northern Italy. Street is calibrated a multiple assessment model composed measures such as closeness, betweenness, straightness. Kernel density estimation used to transform datasets one scale unit for analysis correlation them. Results indicate that retail Bologna tend concentrate areas with better centralities. The distribution these correlates highly global...

Recent theoretical and empirical studies have focused on the structural properties of complex relational networks in social, biological, technological systems. Here we study basic twenty 1-square-mile samples street patterns different world cities. Samples are turned into spatial valued graphs. In such graphs, nodes embedded two-dimensional plane represent intersections, edges streets, edge values equal to lengths. We evaluate local graphs by measuring meshedness coefficient counting short...

The paper examines the geography of three street centrality indices and their correlations with various types economic activities in Barcelona, Spain. focus is on what type (closeness, betweenness straightness) more closely associated which activity (primary secondary). Centralities are calculated purely network by using a multiple assessment model, kernel density estimation method applied to both centralities permit correlation analysis between them. Results indicate that correlated...

We compare the structural properties of street networks ten different European cities using their primal representation. investigate geometry and a set centrality measures highlighting differences similarities between cases. In particular, we found that share due to quasiplanarity but there are also several distinctive geometrical properties. A principal component analysis is performed on distributions centralities respective moments, which used find characteristics by can classify into...

A novel regime of synchronization, called remote where the peripheral nodes form a phase synchronized cluster not including hub, was recently observed in star motifs. We show existence more general dynamical state synchronization arbitrary networks coupled oscillators. This is characterized by pairs that are directly connected via physical link or any sequence nodes. phenomenon almost negligible oscillators as its underlying mechanism modulation amplitude those intermediary between remotely...

In this work we analyze the evolution of voluntary vaccination in networked populations by entangling spreading dynamics an influenza-like disease with evolutionary framework taking place at end each influenza season so that individuals take or do not vaccine upon their previous experience. Our thus puts competition two well-known dynamical properties scale-free networks: fast propagation diseases and promotion cooperative behaviors. results show when is perfect, networks enhance behavior...

Despite the large number of studies on synchronization, hypothesis that interactions bear a cost for involved individuals has seldom been considered. The introduction costly leads, instead, to formulation dichotomous scenario in which an individual may decide cooperate and pay order get synchronized with rest population. Alternatively, same can free ride, without incurring any cost, waiting others his or her state. Thus, emergence synchronization be seen as byproduct evolutionary game their...

In this paper, we study a weak prisoner's dilemma (PD) game in which both strategies and update rules are subjected to evolutionary pressure. Interactions among agents specified by complex topologies, consider homogeneous heterogeneous situations. We deterministic stochastic for the strategies, turn may single links or full context when selecting copy from. Our results indicate that co-evolutionary process preserves networks as suitable framework emergence of cooperation. Furthermore, on...

In this paper we study the evolutionary dynamics of public goods game in a population mobile agents embedded two-dimensional space. framework, backbone interactions between changes time, allowing us to impact that mobility has on emergence cooperation structured populations. Our results point out low degree enhances system. addition, size groups which games are played cooperation. Again find rise and fall related percolation instant interaction networks created by set agents.

Cooperation among unrelated individuals is frequently observed in social groups when their members combine efforts and resources to obtain a shared benefit that unachievable by an individual alone. However, understanding why cooperation arises despite the natural tendency of toward selfish behavior still open problem represents one most fascinating challenges evolutionary dynamics. Recently, structural characterization networks which interactions take place has shed some light on mechanisms...

Many of our routines and activities are linked to ability move; be it commuting work, shopping for groceries, or meeting friends. Yet, factors that limit the individuals’ fully realise their mobility needs will ultimately affect opportunities they can have access (e.g. cultural activities, professional interactions). One important aspect frequently overlooked in human studies is how gender-centred issues amplify other sources disadvantages socioeconomic inequalities), unevenly affecting pool...

Tiny perturbations may trigger large responses in systems near criticality, shifting them across equilibria. Committed minorities are suggested to be responsible for the emergence of collective behaviors many physical, social, and biological systems. Using evolutionary game theory, we address question whether a finite fraction zealots can drive system large-scale coordination. We find that tipping point exists coordination games, whereas same phenomenon depends on selection pressure, update...

The modelling of human mobility is vital for the understanding complexity urban dynamics and guiding effective interventions to improve quality life. Traditional approaches focus on `average citizens,' which overlook multitude experiences from distinct sociodemographic groups. Recent studies have unveiled significant variations in patterns related gender socioeconomic status, yet impact parenthood remains under-explored. Parenthood brings profound changes daily routines, influenced by...

Networks provide an informative, yet non-redundant description of complex systems only if links represent truly dyadic relationships that cannot be directly traced back to node-specific properties such as size, importance, or coordinates in some embedding space. In any real-world network, may reducible, and others irreducible, local properties. This dichotomy persists despite the steady increase data availability resolution, which actually determines even stronger need for filtering...

The containment of epidemic spreading is a major challenge in science. Vaccination, whenever available, the best way to prevent spreading, because it eventually immunizes individuals. However, vaccines are not perfect, and total immunization guaranteed. Imperfect has driven emergence antivaccine movements that totally alter predictions about incidence. Here, we propose mathematically solvable mean-field vaccination model mimic spontaneous adoption against influenzalike diseases expected...

We introduce the use of entanglement entropy as a tool for studying amount information shared between nodes quantum complex networks. By considering ground state network coupled harmonic oscillators, we compute that each node has on rest system. show storing largest are not ones with highest connectivity, but those intermediate thus breaking down usual hierarchical picture classical both numerically and analytically mutual characterizes topology. As by-product, our results point out...

The organisation of a network in maximal set nodes having at least $k$ neighbours within the set, known as $k$-core decomposition, has been used for studying various phenomena. It shown that innermost $k$-shells play crucial role contagion processes, emergence consensus, and resilience system. is decomposition many empirical networks cannot be explained by degree each node alone, or equivalently, random graph models preserve (i.e., configuration model). Here we study some well randomised...

In previous research we defined a methodology for mapping centrality in urban networks. Such methodology, named Multiple Centrality Assessment (MCA), makes it possible to ascertain how each street is structurally central city according several different notions of centrality, as well scales "being central". this study investigate the case Bologna, northern Italy, about much higher statistically "determines" presence activities (shops and services). Our work develops based on kernel density...

Many complex networked systems exhibit volatile dynamic interactions among their vertices, whose order and persistence reverberate on the outcome of dynamical processes taking place them. To quantify characterize similarity snapshots a time-varying network -- proxy for persistence,-- we present study based descriptor named \emph{temporality}. We use average value temporality, $\overline{\mathcal{T}}$, to assess how ``\emph{special}'' is given within configuration space ordered sequences...
